Puller is a special competition car used in drag races.
Dragsters, also commonly called "diggers", can be placed widely in three categories, based on the fuel they use: Gas (Gasoline), Alcohol (methanol), and Fuel (mixture of gasoline and nitromethane). They are mostly single-engine, although dual-engined designs raced in the 1950s and 1960s.
The design of the dragsters evolved from the engine-front rail (named for the open frame rail) from the early days of drag racing, into the "slingshot" (with the driver in between or behind the rear tires, or "slicks") from the early to mid-1960s , became a common "modern" type in the 1970s

Histori
The front engine puller appears because the engine is initially located in the car frame in front of the driver. They do not use (and the current type still does not use) any form of suspension. Because of this, they tend to become unstable with speed. This is because they produce 2,000-3,000 hp (1,491-2,237 kW), coupled with poor tire technology, short wheelbase, and very light weight. (This is shown with extremes in Altered Fuel.) The driver sits tilted back, above the differential in the cockpit located between the two rear tires, a design originating with Mickey Thompson in 1954, as a way of increasing traction. This position causes many drivers to be flawed when disaster clutch failure occurs.
Introduced with the commencement of organized drag races, catapults are limited by the availability of traction from the rear tire or "slick". A number of four-wheel drive dragsters were also tried, including cars by Art Chrisman (along with his brother, Lloyd, and Frank Cannon's partners), Bill Coburn, and Eddie Hill. (Coburn and the Chrisman brothers use twin engines, too.)
Slingshot produced a number of fatal accidents in 1960, including Mike Sorokin's and John Mulligan (months after suffering severe burns in a fire at the Nationals in 1969). Clutches, bellhousings, blowers, and engines explode, with e.t.s hitting 6.43 seconds by the end of 1969; that the pass record is set by Mulligan to pass to # 1 on Nationals. Other accidents include a flip (what today would be called a "blowover") by Jim Nicoll at the 1970 Nationals after the clutch failure.
The superiority of the slingshot, putting weight on the rear tire, is now presented to cause the front end to lift, as the tire technology is improved, to the ballast point, sometimes hundreds of pounds, to be added over the front axle, while others, like Ronnie Scrima Scrimaliner ) and Tony Nancy, will install the wings.
The drawback causes some effort on the rear-engined car. On March 8, 1970, on the Lions Drag Strip, Garlits was driving the Rig Mats XIII, also called Wynnscharger, a catapult rail, when the vehicle suffered catastrophic failure, and the car broke in two in front of the cockpit.
Garlits accidents are like many in the 1960s, and his new design follows some pioneer designs from the rear-engined dragsters (and funny cars, including Doug Thorley and Dave Bowman), among them are Steve Swaja AA/Gas Wedge I from 1963, Roger Lindwall's 1966 Top Fuel Re-Entry, and Dave Miller Drag Wedge (for Andy Granatelli, sponsored by STP) and Kent Fuller fueller Sidewinder III , both in 1969.
The rear engine design proved to be of value in 1970, when Dwayne Ong's Glmore-chassised Pawnbroker won the American Hot Rod Association Summernats on Long Island, New York, the first national win event for a rear-engined car, with a 6.83 at 219 mph (352 km/h).
Garlits returned to Pomona with a new mid-engine car, Rawa Mouse XIV , in 1971. Initially, rodding magazines considered the disadvantages of the new design "clear". Misty Swamp XIV , however, was very successful in 1971, Garlits won two of the top three Top Fuel Erasers (Winternats and Bakersfield), and became runner-up in the Lions, all in the new car.
The rear engineer drags ever since becoming a dragster design standard.
Depending on the class they run, the dragster can be injected or supercharged (or turbocharged), with a variety of machine possibilities. Machines most often come from cars'; some early examples using surplus aircraft engines. Today, they may also be electric.
Dragster is different from "bodied" cars like cute cars and gasser, as well as from altereds.
